You may be wondering why it hasn't been done... I have a theory. The current version of Emerald Lucky Blocks works with something called LootPlusPlus. A mod that's not available within 1.12.2, that's why you and myself ask and these things fall on deaf ears. It's either too complicated to remove, or too time consuming, or the author doesn't exactly know how.

At current, I have just downloaded this Mod, Emerald Lucky Blocks, and am Currently removing all references to Loot plus plus to make it usuable on my 1.12.2 server. I don't claim ownership on the mod... so that's no issue. Though i would love it if the author could throw up a git hub so we could make branches as needed.

So TLDR: It's a pain in the rear to make it updated without the mod it's dependant on updated. The Author should make a git hub so those of us who are skilled can contribute as needed.
